TITLE: Unraveling iron oxides as abiotic catalysts of organic phosphorus recycling in soil and sediment matrices —ABSTRACT: In biogeochemical phosphorus cycling, iron oxide minerals are acknowledged as strong adsorbents of inorganic and organic phosphorus. Dephosphorylation of organic phosphorus is attributed

TITLE: Repression of Microbial Arsenite Uptake and Methylation by Dissolved Organic Carbon —ABSTRACT: Arsenic methylation is the microbe-mediated transformation of inorganic As into methylated species, an important component of the biogeochemical arsenic cycle in rice paddies. Prior to methylation, arsenite

TITLE: Deconstructing synthetic biology across scales: A conceptual approach for training synthetic biologists —ABSTRACT: Synthetic biology allows us to reuse, repurpose, and reconfigure biological systems to address society’s most pressing challenges. Developing biotechnologies in this way requires integrating concepts across

TITLE: Disproportionate carbon dioxide efflux in bacterial metabolic pathways for different organic substrates leads to variable contribution to carbon use efficiency —ABSTRACT: Microbial organic matter turnover is an important contributor to terrestrial carbon dioxide (CO2) budget. Partitioning of organic carbons

TITLE: Phosphorus recycling by mineral‑catalyzed ribonucleotide cleavage on iron and manganese oxides —ABSTRACT: Phosphorus is an essential element influencing both food security via plant fertilization, and water pollution through excessive phosphorus use, yet the phosphorus cycle in ecosystems is poorly

TITLE: Electrostatic coupling and water bridging in adsorption hierarchy of biomolecules at water–clay interface —ABSTRACT: Clay minerals are implicated in the retention of biomolecules within soil organic matter in many soil environments. Spectroscopic studies have proposed several mechanisms for biomolecule

TITLE: Microbially induced precipitation of silica by anaerobic methane-oxidizing consortia and implications for microbial fossil preservation —ABSTRACT: Authigenic carbonate minerals can preserve biosignatures of microbial anaerobic oxidation of methane (AOM) in the rock record. It is not currently known whether

TITLE: An integrated systems-biology approach reveals differences in formate metabolism in the genus Methanothermobacter —ABSTRACT: Methanogenesis allows methanogenic archaea to generate cellular energy for their growth while producing methane. Thermophilic hydrogenotrophic species of the genus Methanothermobacter have been recognized as

TITLE: Physiological and evolutionary contexts of a new symbiotic species from the nitrogen-recycling gut community of turtle ants —ABSTRACT: While genome sequencing has expanded our knowledge of symbiosis, role assignment within multi-species microbiomes remains challenging due to genomic redundancy and

TITLE: Complex regulation in a Comamonas platform for diverse aromatic carbon metabolism –ABSTRACT: Critical to a sustainable energy future are microbial platforms that can process aromatic carbons from the largely untapped reservoir of lignin and plastic feedstocks. Comamonas species present
